Task 21: Configure fabric operating parameters
fabric topology that creates a new path (for example, a new switch is
added to the fabric), frames may be routed over this new path if its
hop count is less than a previous path with a minimum hop count.
This may result in frames being delivered to a destination out of
order since frames sent over the new, shorter path may arrive ahead
of older frames still in route over the older path.
If rerouting delay is enabled, traffic ceases in the fabric for the time
specified in the E_D_TOV field of the Configure Fabric Parameters
dialog box. This delay allows frames sent on the old path to exit to
their destination before new frames begin traversing the new path.
Note that this option is required if Enterprise Fabric Mode (optional
SANtegrity feature) is enabled. Refer to
for details.
Fabric format domain register for state change notifications (RSCNs)
are sent to ports on the switch following any change to the fabric's
active zone set. These changes include activating and deactivating the
zone set, or enabling and disabling the default zone.
When the Suppress RSCNs on Zone Set Activations checkbox
contains a checkmark, fabric format RSCNs are not sent for zone
changes to the attached devices on the switch. Click the check box to
remove or add a checkmark.
Use procedures in this section to set parameters on the switch for
fabric operation through the Configure Fabric Parameters dialog box.
These operating parameters are stored in NV-RAM on the switch.
1. The switch must be offline to change parameters in this dialog
box. If it is not and you activate values, a dialog box displays
prompting you to set the unit offline.
Setting the switch offline terminates all Fibre Channel
connections.
To set the unit offline:
a. Select Set Online State from the Maintenance menu on the menu
bar along the top of the element manager window.
b. When the Set Online State dialog box displays, click Set Offline.
